How many boards are in a cube: types of lumber and features of their calculation
The boards that are used in the construction of houses and other structures differ in several ways. First of all, the material from which they are made is taken into account. The technical characteristics of the product depend on the type of wood. Depending on the production method, these building elements are divided into types:
 edged;
 unedged.
The first of them belong to the highest grade and have the correct shape, since all their faces are amenable to processing. In turn, unedged products are most often used to organize rough flooring, etc. The peculiarity of this material is that its lateral edges are not processed, they contain bark and have a natural shape. This simplifies the production of unedged boards and affects its cost.
In order to answer the question of how to calculate the cube of a board, you must first decide which of the materials will be used in the construction process. For example, it is easier to calculate the cubic capacity and the cost of a cut part, since it has a geometrically correct shape.
For unedged products, there are constant values that are arithmetic mean numbers. The table of boards in a cube in this case is not always suitable, since it takes into account the rounding of even edged lumber.
Separately, it should be said about building materials for finishing. This group includes floorboards, lining, block house and products that imitate timber. The design of these finished parts includes special ribs and grooves necessary for the tight connection of individual elements to each other.
Helpful information! When calculating the finishing lumber, you need to focus only on the dimensions of the main part of the board. Thus, the size of the tool joints is not taken into account, only the numerical values of the product body are taken for the calculation.
Regardless of what type of material is used, a single formula is used to calculate the number of boards in a cube. An exception in this case is unedged products. Their calculation has its own characteristics, because such parts do not have all the faces necessary for the calculation.
Cube volume formula: how many edged boards in 1 cubic meter
A cube is a geometric shape that consists of 6 equivalent faces. Each of them is a square. To determine the volume of this figure, it is necessary to multiply 3 indicators among themselves:
 length;
 width;
 height.
In order to find out how many boards are in 1 cube, you need to multiply several values. The result is a mathematical expression that looks like this:
V = h x b x L, where:
h is the height of the cut product (m);
b  element width (m);
L is the length of one part (m).
Using this formula, you can determine the volume of 1 element. It is important to remember that when carrying out the calculation, it is necessary to translate the millimeter values of the product into meters. For example, in order to determine how many 25x150x6000 boards are in a cube, you will need to convert the numbers by multiplying them by 0.001. The finished mathematical expression after such a transformation will look like this:
V = 0.025 x 0.15 x 6
The result is that the volume of one piece of wood is 0.0225 cubic meters (m³). Next, it remains to calculate how many pieces of edged boards are contained in 1 cubic meter. There is a simple formula for this. It involves dividing 1 cubic meter by the volume of 1 board, which was obtained using the previous mathematical expression. Let's consider the calculation using an example:
1 m³ / 0.0225 m³ = 44.4
Thus, 1 cubic meter contains approximately (if rounded off) 44 boards. After that, it is already possible to independently determine the amount of material required for the construction of a specific structure. And also at this stage, you can make a general estimate indicating the price of edged boards per cube.
To calculate the cost of 1 edged board, a mathematical expression is used, which implies multiplying the volume of 1 part by the price of a cubic meter. Let's take an example:
0.0225 x 8200 rubles. = RUB 184.5
The calculation showed that the cost of 1 edged product will be approximately 184 rubles. If you know the cost of 1 part, but you need to calculate the price of a cube of a board, you need to do the reverse manipulation. In this situation, you will need to divide the price for 1 item (184.5) by its volume (0.0225).
Note! Sometimes, especially when buying a small batch of boards, there is a confusion with the decimal places. In some cases, sellers of sawn timber deliberately expose the cost, calculated when rounded to 3 numbers. However, by law, this value is only suitable for large batches of boards. When purchasing several products, it is recommended to round in accordance with GOST, namely, to 0.000001 m³.
When calculating the number of boards and the cost of lumber per cubic meter, it is advisable to take into account unplanned losses, which very often occur during construction. Therefore, it is recommended to buy edged products with a small stock (several pieces).
How many boards in a cube: calculation of unedged lumber
The calculation of the cubic capacity of an unedged board has some nuances, since its shape is not correct.Such material does not have a rectangular section along its entire length, therefore it is used to organize temporary structures. The lower and upper surfaces of the unedged board must be processed along the entire length. Otherwise, this product is a side part of the log (slab).
There are several methods to find the volume of unedged lumber in 1 cubic meter, as well as its amount. It should be noted right away that determining how many boards are in one cube is rather difficult when it comes to irregular geometric shapes. Therefore, the initial numbers obtained when calculating unedged parts will be an approximate figure.
Consider what methods are used to calculate the volume and the amount of unedged sawn timber:
 batch;
 piece by piece;
 sampling method.
In the first case, you will need to load the lumber into a bag that must have the correct shape. After the bookmark, you need to measure the desired indicators. The following is a standard procedure for determining the volume using the measured values. This method is most common for products that do not have clear edges. For example, it can be used to calculate the cubes of a 25x150x6000 board in a cube (unedged).
It is worth noting that this type of mathematical expression uses a special coefficient (for the width), which is the arithmetic mean. Although this option is not fast, it allows you to answer the question of how to calculate the cube of the board.
The piecebypiece method involves the use of numbers corresponding to the arithmetic mean of the height and width of the trimmed product. These values are calculated in meters.
In order to find the arithmetic mean, it is necessary to measure the board. The minimum width (at the narrowest point) and the maximum are measured. Further, both indicators are added up and divided in half. After that, the same height manipulation is performed. The numbers obtained during the calculation must be multiplied by each other and by the length of the product.
Let's see how this looks like a mathematical expression:
(b max + b min) / 2 x (h max + h min) / 2 x L = V
Using such a formula, it will not be difficult to determine the volume of 1 unedged element and answer the question of how to calculate the cubic capacity of a part. After obtaining this value, you can calculate the total number of boards in a cubic meter. For such a calculation, you will need to use a formula similar to the cut part (a cubic meter is divided by the volume of the product).
Helpful information! When buying raw boards, you need to be careful. Sellers should use a factor that affects the reduction in total volume, taking into account future shrinkage. To calculate wet coniferous products, 1 cubic meter must be multiplied by 0.96. In turn, the coefficient for hardwood is 0.95.
The last way to determine the volume of lumber and its amount in 1 cubic meter is the sampling method. It is used when calculating large batches of wooden building materials. The essence of this method is that several boards are selected from the total mass. Then the parts are measured and calculated in accordance with the piecewise method. The resulting numbers are multiplied by the total number of parts in the batch.
How many boards in a cube 50x150x6000 in a cube: payment
As an example, you can take an unedged product with dimensions of 50 by 150 by 6000 mm. First, we convert millimeters to meters.Some people don't know how many millimeters are in 1 meter. To convert, you need to multiply the required number in mm by a factor of 0.001. In its finished form (with substituted values), the formula will look like this:
(0.155 + 0.145) / 2 x (0.055 + 0.045) / 2 x 6 = V

The main criteria for choosing a finished product. Comparison of prices of wellknown manufacturers.
After adding and dividing by 2, we get the arithmetic average of the width and height of the unedged part. Thus, the formula takes on a more understandable, standard form:
0.15 x 0.05 x 6 = 0.045
This is how the calculation is made, the result of which is finding the volume of 1 board. To determine the number of products in 1 cubic meter, the same formula is used as in the case of an edged analogue.
If necessary, you can calculate the area of one board. Most often this is required when the manufacturer indicates the price per square meter, and not per cubic meter. The area formula involves multiplying the width of a part by its length. It is important in this case not to be mistaken and not to forget to convert millimeters to meters.
In order to determine the cost, the same formula is used as in the case of edged lumber. You just need to multiply the volume of 1 part by the amount that corresponds to the total price of the cube. This is how the cubes are calculated in the cube of a 50x150x6000 board.
Calculating a board using an online calculator
Perhaps the easiest way (along with the lumber cubes table) to determine the exact value of the volume and number of wooden boards is an online calculator. It is a program with predetermined algorithms that allow you to calculate all the required values of lumber. This method makes it possible to calculate not only the edged board, but also other varieties of these products.
Note! In order to avoid the likelihood of an error when calculating the material on the online calculator, you should immediately indicate for which board the measurement is used.
The process itself is quite simple. First, you need to find a calculator on one of the specialized sites using the search line of your browser. Next, you need to enter the necessary indicators in the appropriate cells. The cube board calculator will calculate on its own.
This method is popular and allows you to quickly and accurately determine all the required values of the lumber. When using the calculator, it is recommended to check the filling accuracy several times. In the event of an error, the calculation will be performed incorrectly, which is fraught with serious discrepancies in the final figures.
How many boards in a cube: table (6 meters) and tips for its use
The last method to determine the quantity and volume of wood products is to use a special table. This method is very convenient, since it does not require long calculations. All that is needed is simply to find the desired value in the table using the original data (width, height and length).
In order to quickly find the correct answer to the question of how many boards are in one cube, the table is best suited. However, experts point out one drawback of this method: numbers corresponding to cubic capacity or quantity are often rounded. Therefore, if you need to perform the most accurate calculation, it is recommended to carry out all the calculations yourself.
The volume of edged boards in a cube:
Board dimensions, mm

In addition, before starting the search for the desired value, it is advisable to make sure that the length of the lumber is consistent. The tables can be different, containing information on the cubic capacity of boards with a length of 3, 4 or 6 meters. Today, the most common products are wooden products, the length of which is 6 meters. How many boards are in one cube? The table for determining the amount of lumber also uses rounded values.
Do not forget that the board can be made from different types of wood. Therefore, before starting to use the table, it is recommended to make sure that you have selected the type of lumber you need.

The tabular method is good in that it does not require calculations or selffilling in the overall and other values of the lumber to get an answer. It is suitable for determining the cubic capacity, and also allows you to answer the question of how many boards are in a cube. The table is ideal for calculating large quantities of a product.
Prices of edged boards per cube: 50x150x6000 and other varieties
Today in the construction market you can find many types of lumber. All of them are differentiated not only by size, but also by the type of wood from which they were made. And also the cost of these products is influenced by the production technology and their purpose. In order to find out how much a board cube costs, you need to familiarize yourself with all the varieties of these parts.
The most popular in the construction of private houses, summer cottages, and other structures is the classic edged board. It can be of 1st and 2nd grade. The first option is more expensive because it has higher technical characteristics and durability.
Helpful information! The price for a 1st grade edged board is approximately 7,500 rubles. for 1 cubic meter Products that belong to a lower quality group cost about 46 thousand rubles. for 1 m³.
The width and height of the boards, as a rule, do not affect their cost. This is due to the fact that in a cubic meter, regardless of the dimensions of timber, there will be the same number of parts. In the sense that for the same price you will receive 44 edged boards 25x1500x6000 (price per cube: 7500 rubles) or 22 parts 50x150 having the same length.
Separately, it should be said about edged boards, made in accordance with technical conditions (TU). Lumber of this type costs on average about 7,000 rubles. per cubic meter Such boards have good quality characteristics and can be used in the construction of various structures.
Unedged products are cheaper because they are of lower quality. The calculation of their cost is made using averaged values. The price of unedged sawn timber ranges from 4 to 5 thousand rubles. However, they are not recommended for construction. It is better to use better quality lumber, for example, edged board 40x150x6000 (price per cube: 7500) or similar products with other dimensions.
When buying wood lumber, you need to pay attention to some points. For example, the board must be flat. The curvature of the product most often indicates that the technology was violated during its production. Such parts are not used in construction, as they do not have the required quality.
How much does a board cube weigh? When purchasing this building material, its mass should be taken into account.For example, an edged board made from dry spruce weighs 450 kg (1 cubic meter). 1 m³ of raw product has a mass of 790 kg. Dry pine has a weight of 470, and wet pine  890 kg. This knowledge will be needed when transporting products.
When choosing lumber and calculating it, you need to be careful. The board should not have cracks, chips or other defects. Small cracks are allowed, but it is recommended to buy a solid, highquality product that meets GOST. And also you should pay attention to the presence of knots. This is due to the fact that they negatively affect the strength of the wooden part. The choice of the calculation method depends on the specific case. If necessary, you can always use the services of specialists who will help you perform the correct calculation and make an estimate.
